Abstract

Dumai City is an area located in the coastal area. Processed fishery products are found in Dumai. Processed fishery products are suspected of containing formaldehyde and microbial contamination that can harm health. This study determines the content of formalin and microbes in traditional and value-added processed fishery products in Dumai City. Formaldehyde content was carried out qualitatively with the formaldehyde test kit MERCK and total microbes using the TPC method . The results showed that formalin was found in three samples of traditional and value-added processed fishery products in Dumai City, namely gulama salted fish, salted squid, and crab sticks. As many as 60% of the samples had total bacteria that exceeded the SNI standard, the total bacteria contained were 5.0 x 105 col/gr.

Abstract

Catfish is the main commodity fish smoking in the Kampar area. Increasing the amount of production causes the waste obtained to be higher. If waste is not managed properly it will pollute the environment. Liquid organic fertilizer is an alternative utilization of processing waste. The purpose of this study was to determine the characteristics of the elements N, P, and K in liquid organic fertilizer from catfish processing wastewater. Making liquid fertilizer is done through fermentation techniques. In this case the fermentation was carried out with variations in the time range, 10, 15 and 20 days with variations in the addition of the volume of EM4 microorganisms 0 ml, 10 ml, 20 ml and 30 ml. The catfish waste liquid fertilizer is dark brown to brownish yellow with a pH ranging from 6.65 -7.03. The highest N, P, and K content of catfish waste liquid fertilizer was found to be nitrogen (N) 0.55% with the addition of EM4 30ml with a fermentation time of 10 days, phosphorus (P) 1.01% without the addition of EM4 with a fermentation time of 20 days, and potassium (K) 0.32% with the addition of EM4 30 ml with a fermentation time of 15 days.
